We know that
x²+px−35=0-------> <span>has one root that is equal to 7
so
substitute x=7 in the equation
</span>7²+p*7−35=0
49+p*7−35=0
14+p*7=0
p=-14/7------> p=-2
the answer Part a) is
t<span>he value of the coefficient p is -2
</span>
Part b) <span>Find the other root
</span>x²+px−35=0-----> x²-2x−35=0
<span>
using a graph tool-------> to resolve the second order equation
see the attached figure
the other root is
x=-5
the answer part b) is</span>
the value of the other root is -5<span>

Answer:
$3.49
Step-by-step explanation:
-The z value is calculated by the formula:

Where
are the mean and standard deviation respectively and
is the price of the random selection.
#We substitute and solve for
:

Hence, the mean price of a box of cereal is $3.49
